Just a shameless advertising:
A while ago I created new software for the PropScope. It runs in Linux using Qt5. So should be portable to other systems.
Since the interface protocol is nowhere documented I also created my own software on the scope. Up to now it uses only one COG with a max sapling rate of 1MHz.

Rbehm, that's just awesome. I've wondered for a while if there was a way to get the Propscope working in Linux. It would be neat to run it hooked up to a Pi or something fun like that. The Windows software it comes with is quite functional, but that requires at least something the size of a laptop. (Which isn't really a problem, just the other small, Linux form factors would be kind of fun for a project.)

I have not tried it yet, but I'm afraid that the current version of the GUI might be a too heavy burden on a low power CPU. The graphics eats a lot of power.
Have never played with a Raspi before but I got one last week and will try it.

I suspect a high speed scope display can be created on the Rasperry Pi using Qt and OpenGL ES rendered directly to the frambuffer, no use of X Windows.

A while back I did some experiments with Qt5, gles and the frame buffer on an old Pi 2. It's amazing what it can do.

No doubt that's possible. But my current software relies on qcustomplot to do the waveform and scale drawing and it is a heavy load on the CPU.
To switch to OpenGL would need a big rewrite. This is spare time project and currently I only invest time into it, when I need a feature.
Before investing much time into a redesign for OpenGL I would first get the software on the propscope up to speed: use several COGs to get full 20MHz sampling.

But hey, I made it open source. If anyone wants to chime in you are welcome.

What is the highest frequency the Propscope can realistically work with? If it samples at 25 Mhz, then I assume it must be frequencies well below that. For example, suppose at least ten samples are required peak to peak. That would mean 2.5 Mhz would be the ceiling.

So it would work fine for audio waves, AM broadcast band waves, an 1 Mhz digital, but not work for 10 Mhz frequencies. IS this correct?

If no one has the answer off the top of their head, since I own one, is there a fairly simple way I could test this for you and let you know the result?

Do you have the ability to generate a 2, 5, and 10 Mhz sine waves? If the scope is limited to 2.5 Mhz and below the first one should look good, and the others will look distorted or alias to a lower frequency sine waves.

Sorry for my ignorance, I only ever used the scope to check a signal wire on a truck transmission. Could I generate those with the included DAC card? It says it has "Function generator outputs configurable waveforms between -1.5 to 1.5V and 0 to 5V "

Got any Makefile for your project? I'd like to compile, but can only find a bunch of source code files in your git repo.
